any ideas why my latency is so high?

Test your broadband link

Our measurements found the following characteristics for your link ( -
Downstream Bandwidth: 3996 Kbps Downstream Queue: 142 ms
Upstream Bandwidth: 340 Kbps Upstream Queue: 3651 ms

Your downstream bandwidth is more than 11 times faster than your upstream bandwidth.

Your upstream queue is so large that packets can get delayed for more than a second. This can be a problem for real-time traffic such as VoIP or online games!

For details on our research on broadband networks please refer to our broadband project webpage

A dodgy node somewhere?

Try using the TBB traceroute tool which will show traffic TO you and and oddities in that path.
